Frame structure

Abstract

A frame structure includes a front plate, a middle partition and a back plate. The middle partition is mounted on the backside of the front plate and includes a first side plate portion, a second side plate portion and a third side plate portion extended in the same direction from two opposite ends of the first side plate portion respectively, a stop block protruded from an end of the second side plate portion, an opening formed between the ends of the second side plate portion and the third side plate portion and opposite to the first side plate portion, and the first, second and third side plate portions and the stop block enclose and defining a display object containing space, and a back plate covered onto the rear side of the middle partition. This structure simplifies the operation of changing a display object and improves the convenience of use.

What is claimed is: 
     
         1 . A frame structure, comprising:
 a front plate;   a middle partition, installed at the rear side of the front plate, and including a first side plate portion, a second side plate portion and a third side plate portion extended in the same direction and from two opposite ends of the first side plate portion respectively, a stop block protruded from an end of the second side plate portion towards the third side plate portion, an opening formed between the ends of the second side plate portion and the third side plate portion and opposite to the first side plate portion, and the first side plate portion, the second side plate portion, the third side plate portion and the stop block defining a containing space for placing a display object, and the width from an inner edge of the third side plate portion to an upper edge of the stop block being greater than the width of the display object, and the length from an inner edge of the first side plate portion to an inner edge of the stop block being greater than the length of the display object, so that the display object can be put into the containing space from the opening of the middle partition, and the stop block being provided for limiting the display object from retracting towards the opening from the containing space; and   a back plate, covering the rear side of the middle partition.   
     
     
         2 . The frame structure of  claim 1 , wherein the front plate includes a rectangular frame and a hollow portion formed at the center of the rectangular frame. 
     
     
         3 . The frame structure of  claim 2 , wherein the rectangular frame has a plurality of positioning pins installed at the corners of the rectangular frame, and the middle partition has a plurality of through holes for sheathing positioning pins respectively, and the back plate has a plurality of blind holes for sheathing the positioning pins respectively. 
     
     
         4 . The frame structure of  claim 1 , wherein the back plate has a long slot formed at the backside of the back plate. 
     
     
         5 . The frame structure of  claim 4 , wherein the long slot includes two circular hole portions and a transverse slot portion interconnected to each circular hole portion. 
     
     
         6 . The frame structure of  claim 1 , further comprising a cladding layer covered onto external surfaces of the front plate, the middle partition and the back plate. 
     
     
         7 . The frame structure of  claim 6 , wherein the cladding layer is a paint layer. 
     
     
         8 . The frame structure of  claim 1 , further comprising a cladding layer covered onto an external surface of the front plate and folded and clamped between the middle partition and the front plate. 
     
     
         9 . The frame structure of  claim 8 , wherein the front plate has an embossed frame mounted onto the backside of the front plate, and an inner slot and an outer slot formed at the internal and external peripheries of the embossed frame respectively, and a portion of the area of the cladding layer is hidden and accommodated in the inner slot and the outer slot. 
     
     
         10 . The frame structure of  claim 9 , wherein the cladding layer is a layer of cloth or leather.
